Hi Andrea,

Thank you for your response. Sure I don't CC to libvirt developers.

Please keep the list in the loop, though! I've re-added it.

I am getting an error while creating a Win10 virtual machine using VMM or virt-manager GUI. I could configure the windows 10 quest using its XML file only ofter creating a VM using virt-manager GUI in the following the path /etc/libvirt/qemu.

The modified QEMU emulator is running correctly @ubuntu-kvm3:/usr/local/bin$ ls ivshmem-client qemu-ga qemu-io qemu-pr-helper virsh virt-host-validate virt-pki-validate vmi-dump-memory vmi-process-list vmi-win-offsets ivshmem-server qemu-img qemu-nbd qemu-system-x86_64 virt-admin virt-login-shell virt-xml-validate vmi-module-list vmi-win-guid

This only proves that you've installed it, not that it works. And as I said, the modified binary probably works fine on its own but libvirt might not be able to drive it, at least without tweaks.

@ubuntu-kvm3:/etc/libvirt/qemu$ ls networks

Just for the record, you're not supposed to modify files in /etc/libvirt/qemu directly; use virsh instead.

I couldn't see guest XML file here(because the VM creation was not done). attached snap displaying error while creating a VM.

If you run $ virt-manager --debug from the command line you will get a lot of output, including the XML that's passed to libvirt. Please attempt the installation again, capture that output in a plain text file and send it to the list as an attachment. Also run $ /usr/local/bin/qemu-system-x86_64 -machine help and attach the output of that command, too. That should help us figure out what's wrong. -- Andrea Bolognani / Red Hat / Virtualization
